Question

If the angular measure of an arc is 36 degree & its length is 10 cm, then what is the circumference of the circle ?
​

Answer 1

Answer:

100

Step-by-step explanation:

angle = 36 total angle= 360

therefore arc =10cm total arc i. e circumference =100

Answer 2

Dear Student,

● Answer -

Circumference of circle = 100 cm

● Explanation -

# Given -

Measure of angle = 36°

Arc length = 10 cm

# Solution -

Arc length is calculated by formula -

Arc length = circumference of circle × measure of angle / 360°

Rearranging for circumference,

Circumference of circle = arc length × 360° / measure of angle

Circumference of circle = 10 × 360° / 36°

Circumference of circle = 100 cm

Hence, circumference of circle is 100 cm.

Hope this helps you. Thanks dear.
